The AS handle KISARA-NETWORK-01 is held by Kisara Development LLC.
What it's used for
- The address space carries corporate infrastructure and a specific amateur radio allocation, evidenced by netnames
KSC-DS-01,KSC-NET-02, andAMPRNET(registered to Amateur Radio Digital Communications). - The AS announces 768 IPv4 addresses across 3 prefixes and 36 IPv6 prefixes, with 4 observed neighbours; this low neighbour count relative to the address inventory suggests a business or content network rather than a transit provider.
Notable
- Registrants for the largest prefixes are Kisara Development LLC and Amateur Radio Digital Communications, indicating the space includes both corporate holdings and a distinct radio communications allocation.
- The inventory consists of three /24 IPv4 blocks and ten IPv6 prefixes, with the IPv6 space subdivided into multiple /45, /46, /47, and /48 blocks.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 431 networks and 1,775 prefixes, as published 2026-10-11. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
